Description
This invention relates to antigestagenically active steroids with a
fluorinated 17.alpha.-alkyl chain, process for their production,
pharmaceutical preparations that contain the latter and their use
for the production of pharmaceutical agents.
The invention relates to 17.alpha.-fluoroalkyl steroids of general
formula I
##STR00002## in which R.sup.1 stands for a methyl or ethyl group,
R.sup.2 stands for a radical of formula C.sub.nF.sub.mH.sub.o,
whereby n is 2, 3, 4, 5 or 6, m>1 and m+o=2n+1, R.sup.3 stands
for a free, etherified or esterified hydroxy group, R.sup.4 and
R.sup.5 each stand for a hydrogen atom, or together for an
additional bond or a methylene group, St stands for a steroidal
ABC-ring system of partial formula A, B or C
##STR00003## in which R.sup.6 means a hydrogen atom, a
straight-chain C.sub.1 C.sub.4 alkyl group or branched C.sub.3
C.sub.4 alkyl group or a halogen atom, R.sup.7 means a hydrogen
atom, a straight-chain C.sub.1 C.sub.4 alkyl group or a branched
C.sub.3 C.sub.4 alkyl group, or if St stands for a steroidal
ABC-ring system A or B, in addition R.sup.6 and R.sup.7 together
can mean an additional bond, X means an oxygen atom, a hydroxyimino
grouping .dbd.N--OH or two hydrogen atoms, R.sup.8 means a radical
Y or an aryl radical that is optionally substituted with Y, whereby
Y is a hydrogen atom, a halogen atom, an --OH, --NO.sub.2,
--N.sub.3, --CN, --NR.sup.9aR.sup.9b, --NHSO.sub.2R.sup.9,
--CO.sub.2R.sup.9, C.sub.1 C.sub.10 alkyl, C.sub.1 C.sub.10 alkoxy,
C.sub.1 C.sub.10 alkanoyloxy, benzoyloxy, C.sub.1 C.sub.10
alkanoyl, C.sub.1 C.sub.10 hydroxyalkyl or benzoyl group, and
R.sup.9a and R.sup.9b are the same or different and represent a
hydrogen atom or a C.sub.1 C.sub.10 alkyl group, R.sup.9 is a
hydrogen atom or C.sub.1 C.sub.10 alkyl,
and for --NR.sup.9aR.sup.9b radicals, as well as their
physiologically compatible salts with acids and for
--CO.sub.2R.sup.9 radicals with R.sup.9 meaning hydrogen, as well
as their physiologically compatible salts with bases.
The wavy lines mean that the substituent in question can be in
.alpha.- or .beta.-position.
In the alkyl groups that are mentioned within the scope of this
invention, these are the methyl, ethyl, n- or iso-propyl, n-, iso-
or tert-butyl groups, for example.
The other C.sub.1 C.sub.10 alkyl groups, Y, R.sup.9, R.sup.9a,
R.sup.9b, have the higher homologues in addition, such as, for
example, the pentyl, neo-pentyl, hexyl to decyl groups, for
example.
C.sub.1 C.sub.10 alkyl groups are to be understood to encompass,
however, carbocyclic or alkylcycloalkyl groups as well with up to
10 carbon atoms, for example the cyclopropyl, cyclopentyl,
cycloheptyl, methylcyclopropyl, methylcyclopentyl or
methylcyclohexyl radical. A methyl or ethyl group is preferred for
all cases above.
C.sub.1 C.sub.10 alkoxy, groups are the radicals that are
lengthened by one oxygen atom and derived from the alkyl groups
that are mentioned above, thus, e.g., the methoxy, ethoxy, n- or
iso-propoxy, n-, iso- or tert-butoxy radical.
C.sub.1 C.sub.10 alkanoyl is defined as the acyl radicals of
straight-chain and branched C.sub.1 C.sub.10 alkanecarboxylic
acids, thus, for example, the formyl, acetyl, propionyl, butyryl or
iso-butyryl radical, etc.
C.sub.1 C.sub.10 Alkanoyloxy radicals are the radicals of the above
alkanoyl radicals that are lengthened by one oxygen atom, thus,
e.g., the acetyloxy, propionyloxy, and butyryloxy radical.
If a halogen atom is mentioned as a substituent, this can be a
fluorine, chlorine or bromine atom. Fluorine is preferred.
For radicals R.sup.2, perfluorinated side chains of length n=2 4
are to be preferred and among the latter, in turn the
pentafluoroethyl unit is especially to be preferred.
R.sup.3 stands primarily for a free hydroxy group.
In the case of an etherified or esterified hydroxy group as a
17.beta.-substituent, the latter is preferably etherified with a
C.sub.1 C.sub.10 alkyl group or esterified with a C.sub.1 C.sub.10
alkanoyl group. For this alkyl or alkanoyl group, the same meanings
as above hold true. The etherification or esterification of the
hydroxy group is carried out according to the methods that are
familiar to one skilled in the art.
R.sup.4 and R.sup.5 preferably each stand for hydrogen atoms or
together for an additional bond.
If R.sup.8 is a group Y, this is preferably a C.sub.1 C.sub.10
alkanoyl or (1-hydroxy)-C.sub.1 C.sub.10 alkyl group, whereby among
these radicals, the acetyl and the propionyl group are especially
to be preferred.
Preferred carbocyclic or heterocyclic aryl radicals are phenyl, 1-
or 2-naphthalinyl, 0.2- or 3-furanyl, 2- or 3-benzofuranyl, 2- or
3-thienyl, 2-, 3- or 4-pyridinyl. As substituted aryl radical
R.sup.8 (e.g., substituted one or up to several (e.g., 2 3) times
with Y), primarily 4-cyanophenyl and a 4-halophenyl radical,
especially the 4-fluorophenyl radical, can be cited.
Among all the radicals that are mentioned as preferred for R.sup.8,
R.sup.8 in the meaning of Y and Y in turn equal to acetyl is
especially to be preferred.
The compounds that are mentioned below are especially preferred
according to the invention:

##STR00004##
The establishment of fluorinated side chains in the
17.alpha.-position is carried out analogously to processes that
have been described in many cases for other side chains by
nucleophilic addition of an organometallic compound of formula
MC.sub.nF.sub.mH.sub.o to a 17-ketone of general formula II,
whereby M stands for a metal in the meaning of, e.g., Li, Na, K,
Mg-halogen (halogen=Cl, Br, I) or other metals, and n, m and o have
the meaning that is already indicated in general formula I. To be
preferred is the addition of Grignard reagents
(C.sub.nF.sub.mH.sub.oMg-halogen) or the lithium-organic compounds
such as LiC.sub.nF.sub.mH.sub.o. For the introduction of
perfluorinated side chains, the generation of lithium-organic
reagents starting from the corresponding iodides by means of a
methyllithium/lithium bromide complex (J. Org. Chem. 1987, 52, 2481
and Tetrahedron Lett. 1985, 26, 5243) is especially suitable.
Substituents R.sup.1, R.sup.4, R.sup.5 and St that are mentioned in
general formula II have the meanings that are already indicated in
general formula I, whereby functional groups that are present in St
optionally can be protected according to processes known to one
skilled in the art. Especially carbonyl groups, such as, e.g., the
3-keto groupings, are protected in most cases in a suitable way,
e.g., by the formation of a corresponding ketal or reduction to a
hydroxy group and optionally conversion of this hydroxy group into
an ether or ester.
As a ketal protective group, for example, the ethylenedioxy or the
2,2-dimethlpropylene-1,3-dioxy group can be mentioned. Other
standard keto protective groups are also considered. In the case of
a protected hydroxy group, the latter can be protected, for
example, in the form of methoxymethyl, methoxyethyl,
tetrahydroxypyranyl or silyl ether. By cleavage of the protective
group and oxidation of the free hydroxy group, the keto group is
obtained.
In a suitable stage after the 17.alpha.-side chain has been added,
the protective groups are then removed in a known way and
optionally a hydroxy group is oxidized to the corresponding keto
group.
The addition of the 17.alpha.-side chain can also be carried out in
a selective manner, however, in the presence of other free carbonyl
groups, e.g., also the 3-keto group.
The starting materials of general formula II that are used for the
production of the compounds of general formula I are described in a
whole series of patents, patent applications and publications:
EP-A 0 057 115, EP-A 0 129 499, EP-A 0 259 2489, EP-A 0 186 834,
EP-A 0 447 014; EP-A-0 116 974, EP-A 0 190 759, EP-A 0 147 361,
EP-A 192 598, EP-A 0 283 428, EP-A 0 404 283, WO-A 89/00578, WO-A
91/18917, WO-A 91/18918, WO-A 92/11277, WO-A 92/11278, WO-A
93/23020, Steroids 44 (1984), 349 as well as other relevant
bibliographic references that are known to one skilled in the art
who is active in this field.
In the above-mentioned industrial-property rights, the introduction
of radicals R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8, which
occur there analogously to the radicals that are to be claimed
here, is also described.
In general, the addition of the side chain with a free 17-keto
group can be done at any intermediate stage in synthesis.
If the introduction of the fluorinated 17.alpha.-alkyl side chain
is carried out in an early synthesis intermediate stage, the
establishment of additional radicals R.sup.6, R.sup.7 and R.sup.8
that are mentioned in St can be performed in the presence of this
17.alpha.-side chain according to known processes, as they were
described in, i.a., the above-mentioned patents, patent
applications and publications.
The new compounds of general formula I are valuable pharmaceutical
active ingredients. They are distinguished by a very strong
antigestagenic activity. These are competitive progesterone
antagonists, since they displace the progesterone from its
receptor. At the same time, other endocrine side effects, such as,
e.g., androgenic, estrogenic or antiglucocorticoidal activity are
present if at all, only to a small extent. The compounds can
therefore be used for medicinal purposes.
Compounds with antigestagenic activity (competitive progesterone
antagonists) became known for the first time in 1982 (RU 486=EP-A 0
057 115) and have since been described extensively in, i.a., the
already mentioned patent and bibliographic citations found.
Among the previously disclosed compounds, there are none with a
multiply fluorinated 17.alpha.-alkyl side chain that contains at
least 2 carbon atoms. Only in WO83/03099 is it stated that the
3-keto-.DELTA..sup.4,9-19-nor steroids disclosed there can carry a
17.alpha.-alkyl side chain, which optionally can be substituted
with a halogen atom. Fluorine is not mentioned as a halogen.
Concrete examples with a 17.alpha.-alkyl chain that has at least 2
carbons previously did not exist at all.
Active ingredients of this type with strong antigestagenic activity
are suitable for inducing abortions, since they displace from the
receptor the progesterone that is necessary to maintain the
pregnancy. They are therefore valuable and advantageous with
respect to their use for postcoital birth control.
The compounds of general formula I according to the invention are
also suitable for the production of preparations for female
contraception (WO-A 93/23020, WO-A 93/21927).
In addition, they can be used to counteract hormonal
irregularities, for triggering menstruation and for inducing labor.
Other types of indications in the field of gynecology are the
hormone replacement therapy (WO-A 94/18983), treatment of symptoms
that accompany dysmenorrhea and endometriosis (EP-A 0 266 303) as
well as myomas.
The compounds according to the invention exert strong antitumor
activity in progesterone receptor positive rodent and human breat
cancer models. Antiproliferative activity was observed in vitro in
the human T47D breast cancer cell line. In vivo tumor inhibiting
effects have been proven in the MXT-mammary carcinoma of the mouse
and in the chemically induced mammary carcinoma models of the rat
(NMU: N-nitroso methyl urea; DMBA: dimethylbenzanthracene.
The compounds according to the invention are thus highly suitable
for the treatment of hormone-dependent carcinomas, for example, for
treatment of the progesterone receptor positive mammary carcinoma.
The compounds according to the invention can be used in the therapy
of hormone dependent carcinomas for the first line therapy as well
as for second line therapy, especially after tamoxifen failure.
The antigestagenically active compounds of general formula I
according to the invention can also be used in combination with
antiestrogenically active compounds for the production of
pharmaceutical preparations for the treatment of hormone-dependent
tumors (EP-A 0 310 542), for inducing labor, for termination of
pregnancy and for treatment of gynecological disorders (EP-A 0 310
541) and for female contraception (WO 96/19997). In the treatment
of hormone dependent carcinoma, the antigestagen and the
antiestrogen can be provided for simultaneous or even for
sequential administration. In case of sequential treatment, it is
preferred to administer first the antiestrogen and sequentially
thereto the antigestagen.
Preferred antiestrogens include tamoxifen, the compounds of
EP-A-138,504, especially
7.alpha.-[9-(4,4,5,5,5-pentafluoropentylsulfinyl)nonyl]estra-1,3,5(10)-tr-
iene-3,17.beta.-diol, the compounds of U.S. Ser. No. 08/915,171
(PCT/EP97/04517), especially

zapentadecyl)-estra-1,3,5(10)-triene-3,17.beta.-diol, and aromatase
inhibitors.

The invention thus also relates to pharmaceutical agents that are
based on pharmaceutically compatible compounds of general formula
I, i.e., compounds that are nontoxic in the doses used, optionally
in connection with an antiestrogen together with commonly used
adjuvants and vehicles.
Finally, this invention also relates to the use of compounds of
general formula I, optionally together with an antiestrogen, for
the production of pharmaceutical agents. The compounds according to
the invention can be processed into pharmaceutical preparations for
enteral, percutaneous, parenteral or local administration according
to galenical methods that are known in the art. They can be
administered in the form of tablets, coated tablets, gel capsules,
granulates, suppositories, implants, injectable sterile aqueous or
oily solutions, suspensions or emulsions, ointments, creams and
gels or by means of intravaginal (e.g., vaginal rings) or
intrauterine systems (pessaries, spirals).
The active ingredient or active ingredients can be mixed in this
case with the adjuvants that are commonly used in galenicals, such
as, e.g., gum arabic, talc, starch, mannitol, methyl cellulose,
lactose, surfactants such as Tweens or Myrj, magnesium stearate,
aqueous or non-aqueous vehicles, paraffin derivatives, wetting
agents, dispersing agents, emulsifiers, preservatives and flavoring
substances for taste correction (e.g., ethereal oils).
A dosage unit contains, e.g., about 0.1 100 mg of active
ingredient(s). The dosage of the compounds according to the
invention is approximately 0.1 400 mg per day in humans. Particular
dosages in a given patient can be determined routinely, e.g.,
considering the usual factors such as patient condition, age,
weight, etc. Administration of the compounds is analogous to that
of known antigestagens, e.g., RU 486.
The examples below are used to provide a more detailed explanation
of this invention:
Without further elaboration, it is believed that one skilled in the
art can, using the preceding description, utilize the present
invention to its fullest extent. The following preferred specific
embodiments are therefore, to be construed as merely illustrative,
and not limitative of the remainder of the disclosure in any way
whatsoever.
In the foregoing and in the following examples, all temperatures
are set forth uncorrected in degrees Celsius and unless otherwise
indicated, all parts and percentages are by weight.
The entire disclosure of all applications, patents and
publications, cited above and below, and of corresponding German
application 197 06 061.7, filed Feb. 7, 1997, are hereby
incorporated by reference.
